5562ab3f5a Kernel: Remove some more unnecessary Thread members. 2019-04-20 19:29:48 +02:00
Andreas Kling
b2ebf6c798 Kernel: Shrink Thread by making kernel resume TSS heap-allocated. 2019-04-20 19:23:45 +02:00
Andreas Kling
ec365b82d5 Kernel: Make the colonel run at "Idle" priority (the lowest possible.) 
This means it won't hog the CPU for more than a single timeslice. :^)

ab94a6be00 AK: Add String::copy(BufferType) helper. 
This will create a String from any BufferType that has data() and size().

5eedb22834 Sprinkle use of AK::Vector in various places. 
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__ 
This makes it a bit easier to use AK templates out-of-tree.

e24e486714 Snake: Flesh out a basic snake game :^) 2019-04-20 03:24:50 +02:00

0e6b273620 LibGUI: Start working on GTableView inline editing. 
This is pretty shaky still, but the basic idea is that you subclass GModel
and return true for editable indices. The table view also needs to have its
editable flag set.

3817f5f619 Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9. 
This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)

c02c6fef28 Kernel+ProcessManager: Show per-process syscall counts. 
Added a simple syscall counter to the /proc/all contents. :^)

c59f8cd663 Kernel: Scheduler donations need to verify that the beneficiary is valid. 
Add a Thread::is_thread(void*) helper that we can use to check that the
incoming donation beneficiary is a valid thread. The O(n) here is a bit sad
and we should eventually rethink the process/thread table data structures.

6bb0dbe8bf Kernel: Lock::unlock_if_locked() should never donate to holder. 
Since we're not interested in taking the lock if it's already held,
there's no need to donate the remainder of our time slice to the holder.

33920df299 AK: Try to use StringViews more for substrings and splitting. 2019-04-16 02:39:16 +02:00
Andreas Kling
1debc0a78c Kernel: Reduce kmallocing in all_processes() and all_pids(). 2019-04-16 00:37:35 +02:00
Andreas Kling
2533e0b57b Kernel: Reduce kmallocing in /proc/all and /proc/memstat. 2019-04-16 00:36:17 +02:00
Andreas Kling
88f03f86ff Kernel: Have TTY subclasses cache their tty_name/pts_name. 2019-04-16 00:35:02 +02:00
Andreas Kling
d384c7815f Kernel: Make it possible to have kmalloc() dump call stacks. 
This can be enabled at any time using a sysctl:

    sysctl kmalloc_stacks=1

The stacks will go to the debugger output only.
 2019-04-15 23:58:48 +02:00

fa89446cb6 Kernel: Make symbolication callable from kmalloc(). 
It wasn't possible to symbolicate from kmalloc(), since symbolication would
call kmalloc(). :^)
 2019-04-15 23:50:25 +02:00
Andreas Kling
ae0dc22716 Kernel: Make validate_read_from_kernel() return early for nullptr checks. 
Null pointers are always invalid, so don't bother going through all the
various checks for them.
 2019-04-15 23:48:31 +02:00
Andreas Kling
e9c0f4567d Kernel+ProcessManager: Expose the number of kmalloc/kfree calls. 
This will be very helpful in tracking down unwanted kmalloc traffic. :^)
 2019-04-15 19:43:12 +02:00
Andreas Kling
13041f894f Kernel: Start using StringView in the VFS class. 
The less kmalloc() we can do, the better. Calling kmalloc() disables all
interrupts while it runs, so it's directly affecting responsiveness.
 2019-04-15 14:57:27 +02:00
Andreas Kling
024057b39a Userland: Make sync.sh copy all executables from ../Userland 2019-04-15 13:53:27 +02:00
Andreas Kling
c0fe48635b Kernel: Add /proc/uptime file (number of seconds since boot.) 
Also added a simple /bin/uptime to pretty-print this information. :^)
 2019-04-14 15:19:45 +02:00
Andreas Kling
4132f645ee Kernel: Merge TSS.h into i386.h. 2019-04-14 04:39:56 +02:00
Andreas Kling
3f6408919f AK: Improve smart pointer ergonomics a bit. 2019-04-14 02:36:06 +02:00
Andreas Kling
29d0412a06 Kernel: Remove system.h and make the uptime global a qword. 2019-04-14 01:29:14 +02:00
Andreas Kling
198a1a6877 Minesweeper: Add some menus. 2019-04-13 14:32:18 +02:00

0dbd7b0409 Fix typo in makeall.sh 2019-04-13 13:19:47 +02:00
Andreas Kling
a90e218c71 Minesweeper: Start working on a simple minesweeper game. :^) 2019-04-13 03:08:16 +02:00

6f90f41516 VisualBuilder: Add some more GWidget default properties. 2019-04-12 14:47:21 +02:00
Andreas Kling
0f5114852a Kernel: Spawn text editor by default while I work on it. 2019-04-12 00:58:09 +02:00
Andreas Kling
93b76628a5 GGroupBox: Improve appearance with new FrameShape::Box style. 2019-04-11 14:27:31 +02:00
Andreas Kling
8268ece1bd VisualBuilder: Start working on an interface builder application. 
It's tedious making interfaces programmatically. Let's make a program to
help us with this. :^)
 2019-04-11 00:05:47 +02:00

0bc72551f4 Kernel: Remove two unneeded headers. 2019-04-10 22:49:11 +02:00
Andreas Kling
5e0577a042 Introduce LibCore and move GElapsedTimer => CElapsedTimer. 
I need a layer somewhere between AK (usable both by userspace and kernel)
and LibGUI (usable by userspace except WindowServer.) So here's LibCore.

60a819c14a Kernel: Yet more work on bringing up POSIX SHM. 2019-04-09 02:37:38 +02:00
Andreas Kling
26a06f3fcd Kernel: More work towards POSIX SHM, also add ftruncate(). 2019-04-09 01:10:00 +02:00
Andreas Kling
99f3cc26c3 Kernel+LibC: Add stubs for POSIX shared memory API. 
Specifically shm_open() and shm_unlink(). This patch just adds stubs.
 2019-04-08 23:44:12 +02:00
Andreas Kling
65d6318c33 Kernel: Support non-blocking connect(). 
If connect() is called on a non-blocking socket, it will "fail" immediately
with -EINPROGRESS. After that, you select() on the socket and wait for it to
become writable.
 2019-04-08 04:52:21 +02:00
Andreas Kling
37ae00a4dd Kernel+Userland: Add the rename() syscall along with a basic /bin/mv. 2019-04-07 23:35:26 +02:00
Andreas Kling
8f30657390 Start working on a Downloader app and backing classes in LibGUI. 
LibGUI is slowly becoming LibKitchensink but I'm okay with this for now.

ddba6c1b7f Kernel: Oops, also moved FileDescriptor into FileSystem/, fix Makefile. 2019-04-06 20:34:59 +02:00
Andreas Kling
644c887594 Kernel: Move FIFO into FileSystem/ and Socket+LocalSocket into Net/. 2019-04-06 20:29:48 +02:00
Andreas Kling
ac6c7d3e19 Kernel: Use alloc_fd() more instead of walking fd list manually. 2019-04-06 14:54:32 +02:00
Andreas Kling
a58d7fd8bb Kernel: Get rid of Kernel/types.h, separate LinearAddress/PhysicalAddress. 2019-04-06 14:29:29 +02:00
Andreas Kling
9fbac66a91 Hack sync.sh script to retry umount after a short delay if it fails. 
I keep accumulated unwanted mounts because umount sometimes fails.
 2019-04-05 16:26:29 +02:00
Andreas Kling
329cc60a92 NetworkTask: Add a combined alarm for the all network adapters. 
This way we can go back to snoozing in the receiver task and stop chewing
up the CPU. :^)
 2019-04-05 05:14:20 +02:00

bcc00857a4 AK: Revert Eternal<T> for now since it doesn't work as intended. 2019-04-05 05:14:20 +02:00
Andreas Kling
6df5e3f51a Kernel: Build with i686-pc-serenity-g++. 
This works just fine, and now we only need one cross-compiler. :^)
 2019-04-05 02:56:23 +02:00
Andreas Kling
ec7817af37 Kernel: Spawn /bin/Taskbar on startup. 
I think it's good enough now to be there by default. :^)
